c'o'LLArsIBLE CONTAINER.

Application lved September 11, 1924. Serial No. 737,145.

To all 'whom it may concern.'

Beit known that I, WILLIAM HENRY GREG- oar' GEAKE, a subject of the Kingof Great Britain, residing at- Killara, near Sydney,

in the State of New South Wales, Commonwealth of Australia, haveinvented certain new and useful Improvements in Collapsible Containers,'of which the Afollowing is a specification.

This invention relates to co11aps1ble containers for holding liquidsubstances, especially toilet preparations.

Accordin to my invention, the container is compose of a comparativelyrigid concave top part ot sheet metal provided w1th a central fillingand dispensing orifice, and- `a flexible non-resilient sheet metalconcave lower or `body part of approximately the same size., The twoparts are readily formed by stamping and their adjoining edges arebrought together and secured by a seaming machine so that the edges ofthe top part are turned over `to envelop the opposite edges of the loweror body part. One or both parts may be formed externally with a slightconcavity centrally. The liquid or substance is charged into thecontainer through the dispensing orifice while the upper and lower wallsare nested together as shown in Figure 6, the pressurebf the invadingsubstance progressively bulging thev wall 7, excluding, air from thecontainer and finally testing the integrity of the seam when thecontainer is completely filled, so that if the seam is defective it willburst at the time of the filling, and not later under. pressure of thefingers of the user.

In forming the upper art, the neckof the discharge orifice may eintegral there- 40 with, or IA may punch or make a hole in said part andsecure a neck or the like therein, the orifice in the neck beingclosable by a cap or other means..

The container is substantially spherical or ellipsoidal or an oblatespheroid or ellipsoid, so that the lower part may rest on a table orflat surface and the content extruded through the opening on downward orupward p-ressure being applied. The upper or more rigid part does notbecome distorted and consequently the container never appears unsightly.l

But in order that my invention may be more readily comprehended I willnow describe sameVV with referencel to the accompanying drawings.

Figure l, is a sectional elevation of 'one4 form ofcontainer, the cap orclosure being shewn apart.

Figure 2, is a section in detail, on an enlarged scale, of the edges of'the two parts joined by a seaming machine, the edges of thecomparatively rigid top part 8 being doubled over the edges 12 of thelower part 7.

cent the orifice, for use as a container for shaving cream or the like.

The same numerals indicate like parts throughout the drawings.

7 is the flexible part formed from thin sheet tin, and 8 the morerigidpart 'of' a harder or denser material, the latter having Van orifice 9closable by a suitable cap 10.

The flexible part has; preferably an indentation or concave bottom 11 inorder to facili tate uniformity in the collapse of the walls.

The edges ofibothparts 7 and 8 form -f flanges which are siritablyjoined at12 by a double seam, as illurated in Figure 2, thc walls 7 and8 of the container meeting angularl at the joint and the fianges beingfol ed into' interlocked relationship and compressed togetherv so astobe uid-tight- The edges of the folds are preferably rounded as shownat 12a in Figure 2 to prevent cutting of Ithe soft metal, and the flangeof the rigid wall '8, which is on the outside of the seam, forms anabutment 12b supporting the adjacent part of afiexiblc wall fromexcessive expansion and consequent spreading of the joint.

In the modified form of 4container illustrated in Figures 3 and 4 themore rigid cannot at or riveted at l5 in ,said opening, as illustratedin the@ drawings, the edges 17 and 18' a double seam as in `Figurekbeing joined b 2, when the ower part is nested or collapsed Within theupper part.`

In the form illustrated in Figure 7, the

more rigid part '8 is formed with ade-pression 19 adjacent theA orifice9, in which de pression a quantity of shaving cream or the lie afterbeingfvextruded from the joined, the superposed of said members being ofrelatively hard material and the other of relatively flexible and' softmaterial, the latter being evertible b pressure of itscontents when thereceptacle 1s filled, to form With said superposed member, a chamber.

2. A container for fluent substance comprising dished members joined bya folded 'seam embracing the peripheral edges of both members, thesuperposed of said members being of relatively hard material and.

the other of relatively flexible and soft ma` -terial, evertible bypressure of its contents"` when the receptacle is filled, to form withsaid superposed member, a chamber.

3. A container for fluent substance comrising dished members havingperipheral anges joined by a seam to form a chamber when filled, theWall of said chamber meeting angular-ly at said joint, one of saidmembers being of relative y rigid material andthe other of relativelyflexible and soft material, said flanges being folded into interlockedrelationship the folded layers of 'the seam thus formed being compressedinto fluid-tight contact at'points remote from said joint.

4..-.`A container for fluent substance conrprising dished membershavingperipheral flanges joined by a seam to .form a lchamber when filled, thewalls 'of said chamber meeting angularly at said '0int, one of saidmembers being of relatively rigid material and the other of relativelyflexible and soft material, said flangesvbeing folded into aninterlocked seam in which the edges of the folds are rounded adjacentthe line ofjuncture of saidchamber Walls.

5. A container for fluent substance comprising dished members havingperipheral flanges joined by a seam t'o form a chamber when folded, theWalls of said chamber meetingangularly at said joint, one of saidYmembers being of relatively ri id material and the other of relativelyflexi le and soft material, said flan es beingfolded into in' terlbckedrelations ip, with the relatively rigid flange on the outside, a part ofsaid rigid flange forming an abutment zone surrounding the flexiblemember adjacent said angular joint, supporting the Wall of said memberagainsty excessive expansion and consequent spreading of said joint.

6. A container for fluent substance coinprising upper and lwer dishedmembers peripherally joined to form a chamber when filled, one of saidmembers being of relatively rigid material and the other of relativelflexible and soft material, the upper mem er being formed with'meansforl discharging the contents 4off said container, and recessed to forma basin surrounding said discharge means.' i

7. A container for fluent substance .comprising upper and lower' dishedmembers joined by a folded seam embracing the peripheral edges of bothmembers, to form a chamber when filled, oneof said members being ofrelatively rigid material and the other of relatively flexible and softmaterial, the up er member being formed with means for ischarging thecontents of said container and recessed to form a basin surrounding saiddischarge means.
